IMPROVEMENT IN DOOR-CHECKS.

Specification forming part of Letters Patent No. [75,013, dated March21, 1876; application filed February 23, 1876. I

To all whom it may concern Be it known that I, Simon R. BILLINGS, ofFlint, in the county of Genesee and State of Michigan, have inventedcertain new and useful Improvements in Door-Checks; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings,- which form part of this specification.

My invention relates to an improvement in door-checks, and it consistsin the peculiar construction and combination of the catch and the framein which it is pivoted, as will be hereinafter more fully described anddefinitely claimed.

The accompanying drawings represent my invention.

a, represents the frame or body, which is provided with the perforatedflange, 0, around its base for attaching it to the wall, side of thebarn, or any desired object. In between the two ears or projections, atthe point d, is pivoted the latch e, which has its outer end beveledaway at a, so that it will give before the door, has the recess h, whichcatches over the edge of the door, the projection 13 on its rear edge,which strikes against the body a,

and acts as a stop to prevent it from moving back too far, andtheshoulderj formed on its lowerinside edge. Bearing against thisshoulder is a coiled or other suitable spring, l, which keeps the latchalways pressed forward so that it will instantly spring over the edge ofthe door and hold it, as soonas the door passes the incline g. The frontinner end 0 of the latch also acts as a stop to prevent it from beingforced too far forward by the spring. In the bottom of the body a ismade a hole, n, through which the spring can be removed and replaced atwill.

This check can be used for gates or barndoors wherever the door can beswung around to reach it.

I do not claim,broadly,a catchthat is operated by a spring so as to bemade automatic in its operation but I do claim the peculiar constructionand combination of the parts herein shown and described.

A door-check, consisting of the body a, flanges c, latch e havingincline g, recess h, stop 6, and shoulder j, in combination with thespring I, and hole n, substantially as shown and described.

In testimony that I claim the foregoing, I have hereunto set my hand andseal this 17th day of February, 1876.

SIMEON It. BILLINGS.
